To provide a fluid machinery and an underwater sailing body in which a shroud can be compactified.SOLUTION: A fluid machinery comprises: a shank which extends in an axial direction; a shroud which is arranged covering the shank and which forms a fluid channel between the shank and the shroud in which one side in the axial direction is an upstream side, and the other side in the axial direction is a downstream side; a first propeller which is rotatably arranged around the axial line between the shank and the shroud; a second propeller which is in the downstream side compared with the first propeller and rotatably arranged around the axial line between the shank and the shroud; an outer periphery drive motor which is arranged in the shroud to rotatably drive the first propeller; and an inner periphery drive motor which rotatably drives the second propeller in the opposite direction of the rotation direction of the first propeller.SELECTED DRAWING: Figure 3
【課題】シュラウドのコンパクト化を図ることができる流体機械及び水中航走体を提供する。【解決手段】軸線方向に延びる軸部と、軸部を囲うように設けられて、該軸部との間に軸線方向一方側を上流側とするとともに軸線方向他方側を下流側とした流路を形成するシュラウドと、軸部とシュラウドとの間で軸線回りに回転可能に設けられた第一プロペラと、該第一プロペラよりも下流側で軸部とシュラウドとの間で軸線回りに回転可能に設けられた第二プロペラと、シュラウド内に設けられて、第一プロペラを回転駆動する外周駆動モータと、軸部に設けられて、第二プロペラを第一プロペラの回転方向とは反対方向に回転駆動する内周駆動モータと、を備える。【選択図】図3
